April 9, near Vanuatu and over the next couple of days moved slowly south-eastwards, before it was last noted during April 11, after convection surrounding the system had failed to organize. Tropical Depression 15F developed during April 16, within an area of moderate vertical windshear about to the east of New Caledonia. During that day the depression moved towards the south-southeast before the final advisory on the system was issued, as it left the tropics and convection surrounding the system started to become unorganized. On April 28, a low-pressure area that had developed within the Australian region, was predicted to develop into a tropical disturbance as it moved into the South Pacific basin. During the next day it was classified as Tropical Depression 16F while it was located near New Caledonia, before it was last noted later that day as it moved out of the tropics. The final tropical depression of the season developed during 10 May, within an area of moderate to high vertical windshear, about to the northeast of Avarua on the Southern Cook island of Rarotonga. Over the next day the depression moved towards the southeast, before it was last noted later that day by RSMC Nadi as it moved into TCWC Wellington's area of responsibility.
